To all whom it may concern:

Be it known that I, WILLIAM JosEPH Mo- DONALD, residing at Huntington,Huntington. county, State of WVest Virginia, and belng a citizen of theUnited States, have invented certain new and useful Improvements inOilers with Cast Ductile Casings,

of which thefollowing is a full, clear, and exact description, such aswillxena'ble others skllled in the art to which it appertains to inakeand to use the same, reference'bei'ng had to the accompanying drawings,which illustrate the preferred form of the-invention, though it is to beunderstood that the invention is not limited to the exact details of.construction shown and described,

as it is obvious that various modifications thereof within the scope ofthe claims will occur to persons skilled in the art. In said drawings:v.

It is also intendedthat the oiler shall have acasing of novelconstruction which shall. be given a preliminary form to permit theinsertion. of :valve elements, the initial form beingafterwardaltered'to reliably retain said valveelements. The casing is to be so.formed ofductile material, preferably cast, that itwill comprise, n itsfirst condition a main barrel portion, serving as a houslng for movablevalve elements,

It is also proposed to produce-the oiler piece which shall be proforsuitably interlocking :easily be accomplished A suitable inlet port forlubricant is tobe provided, pref- I erably 1n the tool cooperatingportion ofthe' oiler, and the previouslymentioned longitudinalextensions from the barrel portion are adapted to be arranged so thatthey .;not only cobperate to act as a spring seat and valve; guide, butproduce a series oflubricant egress ports'at the inner end of the oiler.In consequence of the unitary character of the barrel and interlockingportions, the tool-receiving head, the valve seat'and the longitudinalextensions, which latter are subject to rearrangement to admit valveelements and at other times to form a comblned spring seat and Valveguide, to-

gether with the ductilecharacter of thecastlng comprising theseelements, permits a very inexpensive, but thoroughly reliable, oiler tobe produced. Such other advantages-as appear hereinafterare, ofcourse,tobe regarded as com- .ing within the scope of this invention. 1 Referringto the parts, 1 represents the unitary. casing of my improved oilervwhich may beofany suitable ductilermaterial, but

Extensions 4are separated by spaces which partake of the form of notches 5 so thateach individual extension 4 is independent of the others when -;itiprojects longitudinally from the Intermediate the diameter of the sore.threaded portion, the oiler, which has been shoW'n'inFig. '1 to be 5applied to the hub of a mine car Wheel A,

may be adjusted fartherinwardly than it could if the head portion 7 hada greater transverse dimension than the diameter of the threaded portion"6. In some devices in 19 which the oiler is capableof being installed,this more extensive longitudinal adjustment ofit will be of a materialadvantage. Toolreceiving head 7 is provided with an inlet port Savhichswells inwardly from an outer large mouthtoa considerably reduced valveopening; Because of its curvature, the nozzle of any oil can inserted inthe mouth of port 8 will be immediately directed to the inneri'valveopening Without any care onthe part of the person supplying lubricant tothe oiler. V f Directly back of port 8 the metal of casing 1 *lforms avalve seat 9 which is more or less of aspheric con'cavity,-its greatest5 diameter beingcoincident with that of the valve element chamber 3.

In the manutactu re of the oiler the m alleable casting is firstproduced in the form illustrated inFig. 2, and when the longitu- 30dina'l projections 4: from the barrel portion 2 are in the positionsillustrated in'that figure, there is a singleop'ening at-the inner endof the oiler for the insertion of a vvalve 10, provided With a stem 11and a valve actuating spring 12 After the insertion-of these valveelements, the .oiler may be brought into its completed form by bendingthe ductile extensions 4 from the'positions they occupy in Fig. 2 tothose they occupy 40 in Figs. 1, 3 and 5, this requiring but asingle'and simple operation. Because of the ductility of the metal thereis no likelihood of the breakage ofextensions 4, but there is enoughinherent rigidity in the casting so 5 that extensions 4 Will remain inthe positions they are placed in.

After being bent asshown in Fig.3, the extensions 4 reliably retain thevalve elements and forma novel seat for the-valve 5 spring 12, as bestseen in Fig. '5; Extensions 4L-originally were parallel with theaxisofthe casing 1, but in Fig. '5 theyare seen to be radially disposedthereto an'd' to the stem "l-l' o'fvalve 10; The endsof thefextensions*t' now also cooperate to form a guide for stem 11 of valve 10through'which said stem-may reciprocate. After valve 10 has been pushedinwardly for the admission of lubricant, it Will be returned to itsnoree mal position upon the Withdrawal of the nozzle of the'lubricantreplenishing receptacle, and in view of its spherical*head'and "the concave valveiseat 9, valve 10 will bea'utornaticall-yself-centered. Moreover, due

tensions a, egress lubricant ports 13 are present which are annularlyarranged between extensions l, intermediatejthe valve stem 11 andthewall of thejbarrel portion 2 of the ductile casing 1.

The oiler is susceptible of application to many varied devices requiringlubrication and may be applied by being inserted until "its screwthreaded portion 6 engages female threadsiin an aperture provided toreceive it,

after Which it may be screwed farther into and out of the device to belubricated by the I i I i l vhen there is no reason for doing otherwise,it

than the larger head 7'.
